too much engine oil in V70 D5 ?

hello, I was in a factory on Saturday with my v70 d5 mj. 06/04 and had oil changes done there. he put 6l in there, but the manual says 5,5l and the volvo works says 5,8l. what is right now and how harmful is it if there are 200ml too much in there? many thanks!!! groove024
